Theresa Thomas is a Canadian environmental advocate, author, and speaker who helps women and families reduce hidden chemical exposure and create low-toxin homes that support hormonal balance, immune resilience, and emotional well-being.

After a life-altering toxic exposure in the 1990s, Theresa devoted more than 30 years to studying environmental health and endocrine disruption. Her work now supports families with young children, midlife women navigating hormonal shifts, and seniors seeking renewed vitality.

Through practical education and calm, grounded guidance, Theresa teaches how reducing everyday chemical load can restore clarity, steadiness, and confidence at every stage of life.

She is the author of From Toxic to Green: The New Parenting Guide for Maximum Family Health and speaks nationally and online on environmental wellness and healthy home transformation.
